Question

I have an 83 Subaru GL 4wd. It runs normally when it is cold. The choke kicks in and it sounds good while it is warming up. When the engine reaches normal operating temp, it dies. I can keep it running if I keep my foot on the accelerator, but the engines surges. If I don't give it any gas it dies immediately. For some reason, the electric fan wont come on and it eventually gets very hot and boils over. I know the fan motor is good and I have replaced the thermo switch with one from a u-pull it. The thermostat is new also. I have replaced the fuel pump and rebuilt the carb. I also replaced the ignition coil along with a new cap and rotor, but I am still having the same problem. I replaced the fuel pump control unit (rpm sensor) with one from the junkyard to no avail, so I wired the new fuel pump directly in to the fuse block so the fuel pump runs when the key is on. I am at my wits end! I only paid $500 for the car and have spent another $200 since.
